In QPIC, there is no FLASH_BUF_ACC and all the codeword data will

registers which will be used for copying the data from FIFO to
memory. The READ_LOCATION register will be used to read a
specific amount of data from a specific offset within the flash
buffer. It supports sequential offset requests. Each request is
composed of the following fields:
a. Offset within the flash buffer from which data should be
read
b. Amount of data to be read
c. Flag bit specifying the last read request from the flash
buffer. Following the last read request the NANDc refers to the

The QPIC NAND BAM has multiple flags to control the transfer. This
patch adds flags parameter in register and data transfer DMA helper
functions and modifies all these functions call with appropriate
flags using following rule
1. Read and write can’t go in single command descriptor so
separate SGL should be used.
2. For some of the requests, NWD flag should be set in BAM
DMA descriptor.
3. For Data write, the BAM has internal buffer for each codeword.
All write request will modify the data in internal buffer and
this buffer will be flushed to NAND device once EOT flag is set.
So for all the write requests in single codeword, the EOT should
be cleared for all tx data descriptors except the last one.

3. ADM DMA uses only one channel while in BAM DMA, data descriptors

- The BAM transaction contains the array of

The EBI2 NAND controller directly remaps register read buffer with
dma_map_sg and DMA address of this buffer will be passed to DMA
API’s. While, on QPIC NAND controller, which uses BAM DMA, we read
the controller registers by preparing a BAM command descriptor. This
command descriptor requires the
- controller register address
- the DMA address in which we want to store the value read
back from the controller register.
This command descriptor will be remapped with dma_map_sg
and its DMA address will be passed to DMA API’s. Therefore,
it's required that we also map our register read buffer for
DMA (using dma_map_single). We use the returned DMA address
for preparing entries in our command descriptor.
This patch adds the DMA mapping support for register read
buffer. This buffer will be DMA mapped during allocation
time. Before starting of any operation, this buffer will
be synced for device operation and after operation
completion, it will be synced again for CPU.

According to the datasheet of the H27UCG8T2BTR the NAND Technology field
(6th byte of the "Device Identifier Description", bits 0-2) the
following values are possible:
- 0x0 = 48nm
- 0x1 = 41nm
- 0x2 = 32nm
- 0x3 = 26nm
- 0x4 = 20nm
- (all others are reserved)
Fix this by extending the mask for this field to allow detecting value
0x4 (20nm) as valid NAND technology.
Without this the detection of the ECC requirements fails, because the
code assumes that the device is a 48nm device (0x4 & 0x3 = 0x0) and
aborts with "Invalid ECC requirements" because it cannot map the "ECC
Level". Extending the mask makes the ECC requirement detection code
recognize this chip as <= 26nm and sets up the ECC step size and ECC
strength correctly.

This provides an alternative to call the readsl() function that
